I say why not ?
Maidana is a free swinging brawler himself, yes he's smaller than Mayorga, but Maidana was willing to fight Canelo so I could see him going for a fight with El Matador at 154.
He just rejected fighting this 17-0 16 KO's Thurman fella who is a super welter as it wasn't a "tune up" fight.
Mayorga is the tune up for the stars so lets get it on !
Seriously though I think this would be a fun fight, honestly if Maidana stays at 147 there aren't many top guys he can beat there and I like Maidana a lot.
